Kaidu

Kaidu (1230-1301) was the fifth and last Khan of the Mongol Empire, reigning from 1270 to 1301. He reigned as Khan of the Chagatai Khanate from 1270 after seizing power, and after engaging in 30 years of endless warfare against his uncle Kublai Khan and his successor Temur Khan, Kaidu became the last Khan of the Mongol Empire. He was the husband of Nazama and the father of Turandot.

Biography
Kaidu was born in 1230, the grandson of Ogedei Khan and nephew of Kublai Khan. Kaidu ruled Yarkand around 1260 when Marco Polo visited, and his realm was said to be equivalent of a five days' journey. His realm was mostly Muslim, although there were some Christians. He began to have problems with his uncle Kublai Khan and his Ilkhanate allies during Kublai Khan's war with Ariq Boke, and Kublai's supporter Khan Alghu of the Chagatai Khanate ravaged his lands, forcing him to ally with Khan Berke of the Golden Horde. Because Genghis Khan made it a rule that a man needed the consent of all family members to become Great Khan, Kaidu hindered Kublai's attempts to become khagan. Kaidu gained lands of his own during fighting with Kublai's forces, and he convinced Baraq to invade Persia. Although this was defeated, Kaidu succeeded in his plan - Baraq, an enemy of his, was weakened (and died on the retreat to meet Kaidu), and he was made ruler of the Chagatai Khanate that same year, 1270. Kaidu defeated Baraq's sons when they rebelled, and for thirty years he engaged in continuous warfare with Kublai Khan's forces. He died of wounds received in a battle near Karakorum in 1301.
